Arcor (telecommunications)

Arcor is the former name of the fixed phone line and Internet business of Vodafone D2 GmbH, a German subsidiary of telecommunications company Vodafone. It is the second-largest provider of fixed phone lines in Germany after Deutsche Telekom. Its name changed on 1 August 2009 after Vodafone completed acquisition of the company.
Its headquarters are in Eschborn near Frankfurt. It is one of the few telecommunications companies in Germany to operate an ISDN network that is independent of the incumbent provider Deutsche Telekom.

In September 2007 various computer magazines reported that Arcor was blocking access to a small number of pornography sites such as YouPorn for their domestic Internet users. Technology news website Heise Online reported that a competing Internet pornography business had advised Arcor that the blocked sites were illegal under German law as they had either no or inadequate measures to verify the age of people accessing their content.[3]
